VEHICLE-LAMP.

Specification of Letters Patent.

Patented May 21, 1918.

Application filed November 24, 1817. erial N02 203,651.

To all whom it may concern:

Be it known that I, CHARLES McKEEvER, a citizen of the United States, residing at Jersey City, in the county of Hudson and State of New Jersey, have invented an Improvement in Vehicle-Lamps, of-which the following is a specification.

This invention relates to a vehicle lam and more particularly to that type of vehic e lamp in which a cup of transparent or translucent material is employed to surround or the lamp bulb. The invention in the present case resides in the means for securing the cup in position relatively to the lamp bulb which also preferably acts as a means for focusing the rays of light from the lam bulb by the adjustment of the lamp bu b and the socket in which it is fixed as will be hereinafter more particularly described.

In the rawing:

Figure 1 is a central transverse section of a vehicle lamp embodying my present invention.

Fig. 2 is an end view of the cup member.

Fig. 3 is a plan of the resilient spring used both to maintain the cup in position and to act as an auxiliary reflector.

Fig. 4 is an edge view of this spring reflector member, and

Fig. 5 is an enlarged cross section illustrating the modified use of the spring reflector.

Referring to the drawing and particularly to Figs. 1 to 4 inclusive, it will be seen that in carrying out this invention I employ a lamp casing 10 in which there is suitably secured the ordinary reflector 11. The lamp casin 10 is centrally provided with a socket 12 slifiably adjustable in the axis of the lamp in the bearing 13 provided for this purpose in the lamp casing. The socket 12 exteriorly of the lamp casing is adapted, as is customary, to receive a plug 14 by means of which electrical connections are made with a battery or other source of electricity. At the opposite end of the socket within the lamp the same is adapted to receive the base 15 of a light bulb 16. These parts may be secured together by the use of the ordinary bayonet joint ordinarily employed for this purpose or otherwise.

Associated with these parts I employ a cup indicated at 17. This is made of transparout or translucent glass or other similar matcrial and the inner surface thereof may be spitably scored and the outer surface provided with pimples or projections, or the lamp cup may be otherwise made without departing from the nature of this invention. The outer end of the cup is open and at its inner end there is an opening 19 through which in placing the cup In position the base of the light bulb passes. I also employ a resilient member for maintaining the cup 17 in position and as illustrated this prefer ably comprises a disk reflector 18 provided centrally with an opening 20 through which the base of the light bulb also passes and which in order to increase its resiliency is made with a radial slot 21.

As indicated in Fig. 1 of the drawing this spring or resilient reflector may be placed within the cup 17 before these parts are secured in position by passing the base of the light bulb through the openings therein and securing the light bulb in place in the socket 12. The socket 12 is adjustable to position in any suitable manner. As illustrated I have shown the socket provided with a lug 22. Passing through the tapped opening therein is a screw 23 which also passes through a bearing provided therefor 111 a boss 24 in the casing 10, the screw 23 terminating exteriorly thereof in the knurled head 25 by which the screw may be readily turned to move the socket in or out in adjusting the same to the desired position. As illustrated in Fig. l, the socket 12 is moved to its innermost position in which the spring reflector disk lies closely between the light bulb 16 and the adjacent parts of the inner surface of the cup 17 in which position as will be understood, the rays of light from the lamp are contracted and thrown directly forward. It will also be apparent that by moving the socket inwardly the reflector disk due to its resiliency will spread and continue to spread the more the socket is moved in this direction and in so doing the rays of light reflected therefrom will be correspondingly spread, but in all desired positions the resiliency of tllie disk is suflicient to maintain the cup in p ace.

By referring to Fig. 5 it will be seen that instead of placing the resilient reflector disk within the cup 17 I may place the same between the main reflector 11 and the adjacent portion of the outer surface of the cup. In this construction the disk not only maintains the cup in position coacting with the reflector and the light bulb for this purpose, but also acts in the same manner to reflect the rays of li ht as is done when this resilient reflector isk is placed within a cup as shown and described in connection with Fig, 1 of the drawing. 7

I claim as my invention:

' 1. In a vehicle lamp, alight bulb, a socket therefor, a, reflector, a cup member extending entirely ,around the lamp bulb, and a resilient reflector device coacting between the lamp bulb, the cup, and the said reflector for yieldingly maintaining the cup member in position relatively to the lamp bulb and reflector.

2. In a vehicle lamp, a reflector, a light bulb, a sockettherefor, a cup member entirely surroundi the light bulb, and a resilient reflector isk surroundin the base of the light bulb and lying within the cup and between the same and the li ht bulb to yieldingly maintain the cup mem er in position.

3. In a vehicle lamp, a casing, a reflector therein, a light bulb, a light bulb socket adjustable to position, a cup surroundin the light bulb, and a resilient reflector evice coacting between the light bulb and the reflector to maintain the cup in position relatively to the light bulb and reflector.

4. In a vehicle lamp, a casin a reflector therein, a light bulb, a light ulb socket, means for ad usting the light bulb socket to position, a cup surrounding the light bulb, and a resilient reflector device for maintaining the cup in position relatively to the light bulb and reflector, and by the adjustment of the socket to position to determine the focus of the rays of light from the light bulb.

5. In a vehicle lamp, a casing, a reflector therein, a light bulb, a light bulb socket, means for adjusting the light bulb socket to position, a cup surrounding the light bulb, a resilient reflector disk surrounding the base of the light bulb and lying within the cup and between the same and the li ht bulb.
